Hi, So I'm not a new Apple user, and I understand a lot about hardware. I was offered $300 for a Mac Pro 1,1, but I know about the OS Limitations and application support is now up to 10.8 minimum. From what I read, it cannot be upgraded because of the firmware being 32 bit. I've read around how people are modifying this to fool the 10.8 to install and unblacklist the system. Now, I understand that the OS is 64, so is Adobe CC suite, but seeing that the kernel is still 32big regardless of mods, what are the cons to this? I've read a lot of success stories how it works, their system is fast and all. I'm just curious what limitations am I faced when doing the mod? Will it cause apps to not work in 64Bit? I know that only certain upgrades (hardware wise) can be done, but not all. I appreciate any clarification you have on this? I do have the option to spend $400 more on a 2008 model, which I believe is a 2,1 with a 64bit firmware. However this 2006 1,1 model has 16GB of ram (which I plan to upgrade). Thank you!
